1Lamp-based projectors’ brightness and lifetime will vary depending on selected projector mode, environmental conditions and usage. As is common with all lamp-based projectors, brightness will decrease over the lamp lifetime. LED projectors do not have a replaceable lamp and the brightness does not decay significantly over the product lifetime.

2Typical lamp life achieved through testing. Will vary according to operational use and environmental conditions.

High Contrast

Add more depth to your image with a high-contrast projector. With brighter whites and ultra-rich blacks, images come alive and text is crisp and clear.

Full 3D

Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. DLP Link 3D glasses required.


Specially designed lamp modes reduce power consumption by up to 70%. Each mode also improves lamp life, which lowers the total cost of ownership and reduces maintenance.

Quick Resume

This feature allows the projector to be instantly powered on again within 100 seconds of turning it off.

AV Mute

When enabled via remote control or network management, the projector suspends (dims) video output to conserve energy.

Auto Power Off

To help save energy, this feature automatically turns off the projector after a set period of time, if it is not being used.

Full HD 1080p

1080p (1920×1080) resolution renders sharp and detailed images from HD content without downscaling or compression, which is perfect for movies, TV shows and gaming.

MHL Connectivity

Turn your projector into a smart display by connecting your smartphone or tablet with a single cable using MHL; now you can view presentations and documents, stream videos and share photos on the big screen.

RS-232 Control

Take control of the projector using HEX or ASCII commands via RS-232 cable.

Wireless Presenting (optional extra)

Making presentations couldn’t be easier using the optional wireless features of the WPS Wireless Adapter (sold separately) – you can connect and display presentations wirelessly from a laptop, PC or mobile device.

If you hate seeing cables in the classroom, the projectors work with Chromecast adapters. While the $600 DH1012 has a one year warranty, the $900 EH341 is covered for three years. ……

“Its combination of light weight, high resolution, good brightness, and high quality for data images makes it our Editors’ Choice moderately priced, high-resolution projector.”

“If you insist on the best image quality you can get in a portable 1080p projector, however, or the slightly higher brightness level it promises, the EH341 is the obvious pick, as well as our Editors’ Choice.”
